Cool-Power® ZVS Switching Regulators PI33xx-x0 8V to 36VIN Cool-Power ZVS Buck Regulator Family Product Description The PI33xx-x0 is a family of high efficiency, wide input range DC‑DC ZVS-Buck regulators integrating controller, power switches, and support components all within a high density System-in-Package (SiP). The integration of a high performance Zero-Voltage Switching (ZVS) topology, within the PI33xx-x0 series, increases point of load performance providing best in class power efficiency. The PI33xx-x0 requires only an external inductor and minimal capacitors to form a complete DC-DC switching mode Buck Regulator. Device PI3311-x0 PI3318-x0 PI3312-x0 PI3301-x0 PI3302-x0 PI3303-x0 PI3305-x0 Output Voltage Set Range 1.0V 1.0 to 1.4V 1.8V 1.4 to 2.0V 2.5V 2.0 to 3.1V 3.3V 2.3 to 4.1V 5.0V 3.3 to 6.5V 12V 6.5 to 13.0V 15V 10.0 to 16.0V IOUT Max 10A 10A 10A 10A 10A 8A 8A The ZVS architecture also enables high frequency operation while minimizing switching losses and maximizing efficiency. The high switching frequency operation reduces the size of the external filtering components, improves power density, and enables very fast dynamic response to line and load transients. The PI33xx-x0 series sustains high switching frequency all the way up to the rated input voltage without sacrificing efficiency and, with its 20ns minimum on-time, supports large step down conversions up to 36VIN.
